Research on Safety Monitoring Technology of Intelligent Substation Intranet

With the development of smart grid and global energy internet, new information and communication technologies such as big data, cloud computing, Internet of Things and broadband wireless have become the key core technologies of smart grid. As a key node in smart grid, the security of smart substation has a direct impact on the overall security of power system. This paper by analyzing the potential safety hazards that intelligent substations are vulnerable to at present, and enumerates the safety protection technologies applied nowadays, based on the fact that the station control layer of the intelligent substation security protection system is not directly monitored, this paper discusses the application of network security technology in the internal network monitoring of the station control layer of the intelligent substation, and puts forward the concrete scheme.
